基于ATT7022的SVC无功功率补偿集中控制器的研究与设计

摘要

Reactive power and power harmonic are the important factors affecting the stable operation of the power system, which will increase the grid loss in the network transmission, lower power utilization, and affect power quality and equipment life. In the flexible transmission and distribution system, SVC static var compensation is used in the mainstream power grid, and the ATT7022CU chip based on HI-TREND TECHNOLOGY （SHANGHAI） Co. Ltd. is the program to solve the reactive power compensation and harmonic suppression of the power core chip. This paper mainly discusses the design and research of the main controller of SVC based on ATT7022CU.%无功功率与电力谐波是电力系统中影响电压稳定运行的重要因素，它在电网中传输会加大网络损耗，降低电能利用率，影响供电质量与设备寿命。在柔性输配电系统中，SVC静态无功功率补偿是目前电网使用的主流方案，而基于钜泉光电科技（上海）股份有限公司的ATT7022CU芯片是该方案中解决无功功率补偿及电力谐波的抑制的核心芯片。本文主要阐述基于ATT7022CU的SVC主控制的设计与研究。
